用户界面设计中任务建模方法研究*

Model-based user interface design is a new method of designing user interfaces through models.As one of the important models,task model depicts the behaving information of interaction between users and user interfaces.This article introduces five common methods for creating task models:HTA,UAN,GOMS,CTT,Wisdom.We summarize advantages,disadvantages and appropriate enviroment of each method.We also get some future development directions of task modeling me-(thods).
